Check Digit Verification of cas no

The CAS Registry Mumber 501443-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,4,4 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 501443-77:
(8*5)+(7*0)+(6*1)+(5*4)+(4*4)+(3*3)+(2*7)+(1*7)=112
112 % 10 = 2
So 501443-77-2 is a valid CAS Registry Number.

The development of a catalytic synthesis of Muenchnones: A simple four-component coupling approach to α-amino acid derivatives

Dhawan, Rajiv,Dghaym, Rania D.,Arndtsen, Bruce A.

, p. 1474 - 1475 (2003)

A new palladium-catalyzed route to prepare 1,3-oxazolium-5-oxides (i.e., Muenchnones) directly from imine, carbon monoxide, and acid chloride building blocks has been developed. This provides a straightforward catalytic synthesis of Muenchnones and is ame
